[Dxspider-support] Abusive show/heading commands

[Stephen Carroll]

John,

This issue was discussed about a year ago, search the listserver archives.
A few of us were actually in contact with the software author at that time,
but I don't have his email address anymore. In the end, not much changed
after numerous emails back and forth. Again, good luck!
